Quake on the older Amigas

VRAM bus speeds. I get deja vu every time this comes up :lol:

Quake on 680x0 is only really feasable on 68060. It's mostly the calculation overhead that kills it - VRAM speed is a secondary concern that has more impact once you move to PPC / GL.

I have a BPPC 040 25MHz and BVision. Under AGA it managed around 3-4 fps, peaking at 6. On the BVision it also managed about 3-4fps, peaking at 6. In this case the AGA speed / C2P time was not the limiting factor at all. It was already so slow that simply rendering the frames killed it.

To really enjoy (software only) quake on 680x0, use a CSMK3 060 and a graphics card (preferably on as fast a bus as possible). I've seem  almost 20fps on such a setup.

GLQuake2 on 68060 is also rather playable, if you have a supported 3D card. GLQuake1 is actually slower than GLQuake2 largely because GLQuake1 was a hack whereas Quake2 was written from the ground up with GL support in mind.

It is, but Quake will bring both very much to their knees. The 3-4fps was for 50% screensize.

You should play NTSC if possible - 320z200 will give you a bit faster FPS.

On my BPPC, WarpQuake ran nicely at 320x400 (NTSC laced) on AGA, getting about 15-20fps fullscreen.
